There are two reasons for the leaf plate cracking
First, the leaf plate is too thin, the structure itself can not withstand the distortion of the front beam head
Two, the lower limit size is not right, the tire first top to the leaf plate when the strong bump down "hit", the lower arm limit works lag.
In view of these two problems, under the guidance and research of howler version and straight version:
We made the following adjustments
1, prepare welding to strengthen the leaf plate, not the whole steel plate for welding, that will interfere with the distortion and deformation of the leaf plate itself, we use the method of reinforcing steel "mesh", which can maximize the retention of the leaf plate original (due) deformation, but also can do the strengthening of the leaf plate itself
2. Increase the lower arm limit within a certain range to make the lower arm limit work earlier in the process of vehicle jumping, so as to avoid the hard contact between the tire and the leaf plate often.
